Case IH 140 Combine Parts
140 parts and accessories
The Case IH 140 combine harvester, manufactured from 1978 to 1982, was a popular choice for farmers seeking a reliable and efficient machine. Powered by a 140 HP engine and available with header widths up to 20 feet, the 140 was known for its dependable conventional separator system. Its simplicity and robust design made it a workhorse in fields across the grain belt.
The Case IH 140 combine was introduced in 1978 as part of Case IH's 40 series, replacing earlier models and offering improved performance and efficiency. Production continued until 1982. It was equipped with an International Harvester DT-414 6.8L six-cylinder diesel engine producing approximately 140 horsepower. The threshing system utilized a conventional cylinder with a 37.5-inch width and a 22-inch diameter, along with a straw walker system for separating grain from the straw. The grain tank held around 135 bushels, and the unloading auger could unload at a rate of about 35 bushels per minute. Available header widths ranged from 13 to 20 feet, offering flexibility for different field sizes and crop types. While a dedicated chopper/spreader wasn't standard, aftermarket options were often added. The cab was functional, providing basic operator comfort and controls. The Case IH 140 excelled in harvesting crops like wheat, soybeans, and corn, especially in situations where a simpler, mechanically sound machine was preferred.
